It shouldn't be a good sub amp with only 4 output devices per channel, but it is, the best for pace I know of so far, but then again, I haven't tried a Krell, Levinson, or other for a sub amp either.

Can find them used for about a kilobuck.

Kenwood LO7M (vintage from the 80's). DC coupled from input to output, and super for a SW amp. (Lots of luck finding one).
Crown K1. Easy to drive, gobs of power, can be found cheap used, no fans, awesome bass.
